The major classes of lipoproteins migrate electrophoretically according to their charge as well as their size, shape, and interaction with the supporting medium. Although HDL-C, LDL-C, and VLDL-C measurements have generally displaced lipoprotein electrophoresis, it continues to be important for assessing postheparin lipolytic activity. Also, a small chylomicron band at the origin signals a non-fasting state in a patient and LPE also detects LP-X, an abnormal lipoprotein that is a marker in obstructive jaundice.

Patient preparation:

The assay manufacturer Beckman Coulter advises: "N-Acetyl Cysteine
(NAC), when administered in therapeutic concentrations (for the
treatment of acetaminophen overdose), has been...determined to
interfere with assays for...Cholesterol, Uric Acid" where "NAC
interference may lead to falsely low results." According to
Beckman Coulter, the NAC interference should be insignificant by
12 hours after completion of the initial loading dose of an IV
infusion treatment regimen consisting of an initial loading dose
of 150 mg/kg administered over 1 hr, a second dose of 50 mg/kg
administered over 4 hrs and a third dose of 100 mg/kg administered
over 16 hrs.
